Abstract
The utility model belongs to the technical field of automobile braking, and particularly relates to a drainage synchronization relay valve which comprises a valve cover, a middle valve body and a lower valve body. A control air inlet is formed in the valve cover, a brake air outlet is formed in the lower valve body, a drainage device is arranged on the bottom portion of the control air inlet and comprises a drainage cavity, a packing cup is arranged on the top portion of the drainage cavity, an exhaust hole is formed in the bottom portion of the drainage cavity, and a heating device is arranged outside the drainage device. The drainage device is arranged, the relay valve can be guaranteed to be communicated with the outside without braking, and water vapor condensation is reduced. In the process of braking and braking reliving of the relay valve, remaining gas and internal accumulated water in the relay valve can be discharged out through the exhaust hole. The heating valve can prevent the accumulated water of the relay valve from being frozen when temperature is low in winter, and the safe and convenient operation of vehicles is guaranteed.
Description
Technical field
The utility model relates to a kind of draining synchronous relay valve, belongs to the automobile brake technical field, two bridge cars, rear three bridge car and trailers after mainly should being applied to.
Background technology
Along with the development of Domestic Automotive Industry, long-distance vehicle becomes development tendency in recent years, especially partly pulls automobile and occupies most of freight market.Semitrailer vehicles mostly adopts Pneumatic brake valve to control the braking of vehicle, there is for a long time inner product water problems in the brake activation valve use procedure always, under needing irregularly brake activation valve to be taken apart removing inner ponding, particularly winter temperature, cause brake piping to freeze, vehicle can't normally travel.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of simple in structure, conveniently realize that the pipeline internal water accumulation gets rid of automatically, pipeline freezes and automatically removes, and then can guarantee the draining synchronous relay valve of vehicle safety operation.
Draining synchronous relay valve described in the utility model, comprise valve gap, middle valve body and lower valve body, valve gap is provided with the control admission port, on lower valve body, the braking air extractor duct is set, control the admission port bottom and be provided with freeing arrangement, freeing arrangement comprises drain chamber, and leather cup is installed at the drain chamber top, bottom arranges deflation hole, and freeing arrangement is installed heating arrangement outward.
Cup leather packing is arranged in drain chamber, and when not braking, the leather cup in valve body is in free state, is positioned at the drain chamber top; Install PTC quartz conductor automatic constant-temperature original paper on valve body additional, temperature is controlled at 70 degrees centigrade; Under the needs brake condition, brake gas promotes leather cup and moves downward, and by the sealing of the deflation hole of drain chamber, brake gas is imported in synchronous relay valve simultaneously; When decontroling braking, because intake pressure reduces gradually, the gas that now valve inner will be arranged backs down leather cup, residual gas is discharged from deflation hole, if having ponding also can discharge in the lump from here, lower than zero degrees celsius the time, open the valve body heating arrangement when the cold external temperature of weather, can effectively prevent the icing phenomenon that cold causes.
Described heating arrangement is the PTC heating plate.The PTC heating plate is easy to use, safe.
In described middle valve body, pressure regulating valve is set, pressure regulating valve comprises and regulating the valves, and regulating spring is installed at the top that regulates the valves, and adjusting screw(rod) is arranged at the regulating spring top, regulate the valves be communicated with in the valve body air cavity.The gaseous tension that adjustable device inside is set of pressure regulating valve, make working process safe and reliable.
Adjustable throttling is installed in described braking air extractor duct.But the air output of adjustable brake air extractor duct, reach gently stop gentle, heavy brake is clever, the braking effect of the tire of not dawdling.
The beneficial effects of the utility model are:
By freeing arrangement is set, can make can guarantee that relay valve communicates with the external world by deflation hole under the brakeless state, reduced the cohesion of aqueous vapor; In the process of braking in braking and the releasing of relay valve, by deflation hole, the residual gas of relay valve inside and inner ponding can be discharged; When heating arrangement can prevent that winter temperature is low, the ponding of brake activation valve freezes, and guarantees the safe ready operation of vehicle.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross sectional view of A-A in Fig. 1.
In figure: 1, adjusting screw(rod) 2, regulating spring 3, regulate the valves 4, adjustable throttling 5, lower valve body 6, braking air extractor duct 7, middle valve body 8, valve gap 9, PTC heating plate 10, control admission port 11, leather cup 12, drain chamber 13, deflation hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Fig. 1～Fig. 2, draining synchronous relay valve described in the utility model, comprise valve gap 8, middle valve body 7 and lower valve body 5, valve gap 8 is provided with controls admission port 10, and braking air extractor duct 6 is set on lower valve body 5, controls admission port 10 bottoms and is provided with freeing arrangement, freeing arrangement comprises drain chamber 12, leather cup 11 is installed at drain chamber 12 tops, and bottom arranges deflation hole 13, and freeing arrangement is installed heating arrangement outward.Heating arrangement is PTC heating plate 9.The interior pressure regulating valve that arranges of middle valve body 7, pressure regulating valve comprises and regulates the valves 3, and regulating springs 2 are installed at 3 tops that regulate the valves, and adjusting screw(rod) 1 is arranged at regulating spring 2 tops, valve body air cavity in 3 connections that regulate the valves.The interior installation adjustable throttling 4 of braking air extractor duct 6.
Working process:
Under the needs brake condition, brake gas promotes leather cup 11 and moves downward, leather cup 11 is by 13 sealings of the deflation hole of drain chamber 12, brake gas is imported in synchronous relay valve simultaneously, when gas arrives braking air extractor duct 6, regulate airshed through adjustable throttling 4, can reach the purpose gentle, that heavy brake is clever of gently stopping.
When decontroling braking, because intake pressure reduces gradually, the gas that now the synchronous relay valve valve inner will be arranged backs down leather cup 11, residual gas is discharged from deflation hole 13, if having ponding also can discharge in the lump from here, lower than zero degrees celsius the time, open PTC heating plate 9 when the cold external temperature of weather, can effectively prevent the icing phenomenon that cold causes.
